DC-AC Frequency Converter Type Nose Cleaner
Abstract
A DC-AC frequency converter type nose cleaner includes an
electromagnetic pump, a container storing a cleaning solution, a
nose-washing tool and a frequency converter circuit driving the
electromagnetic pump. The frequency converter circuit at least
includes an oscillator circuit, a bistable circuit and a push-pull
circuit. The electromagnetic pump is supplied with AC obtained from
the oscillation of DC in the frequency converter circuit. The swing
speed, the swing frequency and the swing amplitude of the swing
arms vary with the change of the oscillation frequency of the
oscillator circuit. Thereby, the discharge pressure and the
discharge flow of the electromagnetic pump could further be changed
to obtain the most appropriate discharge pressure and discharge
flow of the nose cleaner. In other words, the DC-AC frequency
converter type nose cleaner can change the pressure and the flow
generated by the electromagnetic pump so as to satisfy the
requirement of the discharge pressure and flow of the nose cleaner
so as to overcome the defect of the discharge pressure of the
conventional nose cleaner that is too big to hurt the user.

Description
FIELD OF INVENTION
[0001] The present invention relates to a DC-AC frequency converter
type nose cleaner, and more particularly to a nose cleaner with an
electromagnetic pump supplied with AC power obtained from the
oscillation of DC power, herein the speed, the frequency and the
amplitude of the swinging of the swing arms of the electromagnetic
pump vary with the frequency of the switching between the N-phase
and the S-phase of the electromagnetic device, thereby the
discharge pressure and the discharge flow generated in the
electromagnetic pump will satisfy the requirement of the nose
cleaner.
DESCRIPTION OF RELATED ARTS
[0002] Most of upper respiratory tract infections, including
nasosinusitis and nasal allergies, are caused by the ataxia of the
cilia on the nasal mucosa. The contaminants and the bacteria drawn
in through the nose can be effectively removed by the regular
movement of the cilia on the nasal mucosa, thereby protecting the
health of the individual.
[0003] The nasal sprayers commonly on sale in the market or used
for "ear-nose-throat" ailments treatment (hereinafter, "ENT
ailments") mainly utilize ultrasonic vibrations to atomize the
liquid medicines into micro particles so that the atomized
medicines can rapidly and easily be breathed into the respiratory
tracts and the lungs of the human bodies for a desired treatment.
However, these nasal sprayers cannot substantially mend the ataxia
of the cilia.
[0004] Accordingly, a conventional nose cleaner has been invented.
As shown in FIG. 9, when using the nose cleaner, the user has to
bend his head downward, open the mouth and breath, and then a
nose-washing tool is used to inject the cleaning solution about
35.degree. C. to 38.degree. C. or warm salt water into the nasal
cavity of one side of the nose. The cleaning solution flows through
the nasopharynx and flows out from the nasal cavity through the
other side of the nose, thereby the cleaning assists the movement
of the cilia on the nasal mucosa. That is helpful in the prevention
of colds, allergic rhinitis, nasosinusitis, halitosis, backflow of
the snot, and etc.
[0005] Currently, the technology of the nose cleaners still focuses
on the control of the intensity of the water flow. Although the
water flow with a high pressure will provide better cleaning, it
may cause a choke or cause damage to the nasal mucosa or even cause
severe pain to the one with sinuses swollen, which may further
cause a secondary damage. If the pressure of the water flow is too
low, the effect of the cleaning will be reduced. As the proper
intensity of the water flow varies from person to person, it is
hard for the producers to handle.
[0006] Referring to FIGS. 1-7, an electromagnetic pump 20 is
disclosed, which could also be called as a swing arm pump or a
matrix type pump. The electromagnetic pump 20 is light in weight
and could be operated with less noise, lower power consumption and
little chance to generate a high heat, and the electronic circuit
of the electromagnetic pump is hard to shot when the inlet and the
outlet channels are blocked. Hence, the electromagnetic pump
mentioned above is a good choice for being used as the power of
medical apparatus and instruments. The electromagnetic pump 20 has
an electromagnetic device 27 on one side and a pump housing 21 on
the other side. Each of two outer opposing sides of the pump
housing 21 provides a stretchable and elastic bladder 24, which
further provides a swing arm 25 respectively thereon, wherein one
end of each swing arm 25 is disposed on the outer side of the pump
housing 21 and a magnetic member 26 is provided on the other end of
each swing arm 25 with a distance from the electromagnetic device
27. The inside of the pump housing 21 is divided into two chambers
211 and 212, wherein the first chamber 211 is communicated with two
inlet tubes 22 and the second chamber 212 is communicated with two
outlet tubes 23. Referring to FIGS. 2 and 3, the electromagnetic
device 27 has two side magnetic members 271 and a middle magnetic
member 272, wherein the magnetism of the three members alternate
between N-phase and S-phase. The two magnetic members 26 are
disposed opposite to the two side magnetic members 271 respectively
and have N-phase outside surfaces and S-phase inside surfaces
respectively. As shown in FIG. 2, when the two side magnetic
members 271 of the electromagnetic device 27 switch to N-phase and
the middle magnetic member 272 switches to S-phase, the two
magnetic members 26 are attracted by the middle magnetic member 272
and are repulsed by the two side magnetic members 271 to bring the
swing arms 25 towards the middle. Oppositely as shown in FIG. 3,
when the two side magnetic members 271 of the electromagnetic
device 27 switch to S-phase and the middle magnetic member 272
switches to N-phase, the two magnetic members 26 are repulsed by
the middle magnetic member 272 and are attracted by the two side
magnetic members 271 to bring the swing arms 25 towards the
outside. The speed, the frequency and the amplitude of the swinging
of the swing arms are relative to the predetermined frequency of
the power source, and are also relative to the discharge pressure
and the discharge flow.
[0007] Referring to FIGS. 4-7, when the swing arms 25 swing towards
the outside to expand the bladders 24 respectively, the two first
check valves 241 respectively provided between the pump housing 21
and the bladders 24 are set to open to allow a fluid flow into the
first chamber 211 through the inlet tubes 22 on the outside of the
pump, substantially the fluid flows into the two bladder 24 and
then is stopped from flowing into the second chamber 212 by two
second check valves 242, as the two second check valves 242 are
turned off. And when the two swing arm 25 swing towards the middle
to compress the two bladders 24 respectively, the two second check
valves 242 are turned on and the first check valves 241 are turned
off, hence the fluid in the two bladders 24 could only flow into
the second chamber 212, but reflow back into the first chamber 211,
substantially the fluid in the second chamber 212 is discharged
from the pump housing 21 through the two outlet tubes 23. With the
designs mentioned above, the pump housing 21 draws a fluid from the
inlet tubes 22 and then discharges the fluid from the outlet tube
23 to accomplish the transporting of the fluid. As shown in FIG. 8,
connect the outlet tubes 23 to a nose-washing tool 50, then the
nose-washing tool 50 could be used to clean the nose.
[0008] The electromagnetic pump 20 must be supplied with AC to
drive the two swing arms 25 to swing forth and back. However, as
the voltage of the domestic electricity used in the countries
worldwide is 110V or 220V, for example, the domestic electricity in
Taiwan is single phase electricity with a voltage of 110V and a
frequency of 60 HZ. When alternating electricity of 110V and 60 HZ
is used as the power source of the electromagnetic pump 20, the
speed, the frequency and the amplitude of the swinging of the swing
arms 25 of the electromagnetic pump 20 are fixed and could not be
adjusted due to a combined effect of the magnetic field strength
generated in the electromagnetic device 27, the length and width of
the swing arms 25, the magnetic strength of the magnetic members 26
and the elasticity of the bladders 24. That means the pressure and
the flow of the discharge of the electromagnetic pump 20 could not
be adjusted according to the requirement of the pressure and/or the
flow. Hence, when the electromagnetic pump 20 is applied to the
nose cleaner, the discharge force might be so large to cause a
choke or cause damage to the nasal mucosa and the sinuses, or be
too small to clean the nasal cavity well.
[0009] Referring to FIGS. 8 and 9, a nose-washing tool 50 of the
prior art has a hollow handle 51, an extension tube 53, a connecter
52 disposed on the top end of the handle 51 for communicating with
the extension tube 53, a spray nozzle 54 communicated with the
extension tube 53, and a fluid inlet connecter 55 disposed on the
bottom end of the handle 51 for supplying the cleaning solution or
physiological saline or warm salt water, wherein the fluid inlet
connecter 55 and the extension tube 53 are communicated with each
other inside of the handle 51, thereby, when switch a button 56 of
the handle 51, the spray nozzle 54 could be controlled to drain the
cleaning solution or not. When using the nose cleaner, the user has
to bend his head downward, open the mouth and breath, and then
switches the button 56 to control the spray nozzle 54 to inject the
cleaning solution into the nasal cavity of one side of the nose.
The cleaning solution flows through the nasopharynx and flows out
from the nasal cavity through the other side of the nose, thereby
the cleaning assists the movement of the cilia on the nasal mucosa.
That is helpful in the prevention of colds, allergic rhinitis,
nasosinusitis, halitosis, backflow of the snot, and etc.
[0010] Hence, the traditional nose-washing tool 50 has several
defects in use. For example, if the user has nasosinusitis or could
not make an autonomous respiration, then a choke will happen. For
example, when the user feels it is too slow to close the cleaning
solution by switching the button, the user always draws the
nose-washing tool 50 out to quickly draw the spray nozzle 54 out
from nasal cavity, and then the cleaning solution will splash out
to the ground or the user's body. Hence, a nose cleaner and its
accessories are required to be improved to satisfy people's
requirements.
SUMMARY OF THE PRESENT INVENTION
[0011] According to the drawback of the current nose cleaner could
only use the electromagnetic pump supplied with the 110V AC as the
power source, the present invention provides an electromagnetic
pump that substantially accomplishes the following advantages and
objectives.
[0012] The invention is advantageous in that it provides a nose
cleaner with a frequency converter circuit, which oscillates to
convert DC into AC supplied to an electromagnetic pump of the nose
cleaner, wherein the frequency of the oscillation of the frequency
converter circuit is able to be changed to adjust the discharge
pressure and the discharge flow of the electromagnetic pump in
order to obtain a most appropriate discharge pressure and flow of
the nose cleaner.
[0013] Another advantage of the invention is to provide a nose
cleaner which uses a general-purpose power source, such as battery,
in-car cigarette lighter, transformer rectifier unit (TRU) or the
other suitable device providing DC, and thus the nose cleaner could
be widely used in any place with a suitable power source.
[0014] Another advantage of the invention is to provide a nose
cleaner with a frequency converter circuit, which further links to
a modulation circuit, wherein when the swing arms swing outward,
the modulation circuit is activated to accelerate the swing speed
of the swing arms to further enlarge the discharge pressure of the
electromagnetic pump, thereby the discharge pressure of the nose
cleaner is various and adjustable, and could be adjusted according
to the user's requirement.
[0015] Another advantage of the invention is to provide a
nose-washing tool having a touch sensitive switch, which could
close the injection of the cleaning solution immediately just after
the nose-washing tool leaves the nasal cavity, when the user has a
choke, as a result the nose-washing tool overcomes the splashing
out defect of the cleaning solution of the traditional nose-washing
tool.
[0016] Additional advantages and features of the invention will
become apparent from the description which follows, and may be
realized by means of the instrumentalities and combinations
particular point out in the appended claims.
[0017] According to the present invention, the foregoing and other
objects and advantages are attained by a nose cleaner comprising an
electromagnetic pump, a frequency converter circuit, a nose-washing
tool, and a container for storing a cleaning solution. The
frequency converter circuit oscillates to convert DC into AC, which
is supplied to the electromagnetic pump.
[0018] The electromagnetic pump has an electromagnetic device on
one side and a pump housing on the other side, wherein at least one
outside surface of the pump housing provides a stretchable and
elastic bladder, which further provides a swing arm thereon. One
end of the swing arm is disposed on outer side of the pump housing
and a magnetic member is provided on the other end of the swing arm
with a distance from the electromagnetic device. The inside of the
pump housing is divided into two chambers, including a first
chamber having at least one inlet connecter for communicating
inside and outside and a second chamber having at least one outlet
connecter for communicating inside and outside, wherein the first
chamber and the second chamber are arranged up and down, or forth
and back. A check valve is provided between each chamber and
corresponding bladder. The swing arms swing reciprocatingly to
cause the electromagnetic pump drawing a fluid into the chambers
from the inlet connecter and discharge the fluid from the outlet
connecter. The inlet connecter of the electromagnetic pump is
communicated with a container for storing cleaning solution, and
the outlet connecter of the electromagnetic pump is communicated
with a nose-washing tool, wherein the electromagnetic pump could
draw the cleaning solution in the container into the chambers of
the electromagnetic pump through the inlet connecter and then drain
the cleaning solution out from the nose-washing tool through the
outlet connecter, wherein the cleaning solution drained from the
nose-washing tool is used to clean the nasal cavity.
[0019] The frequency converter circuit comprises an oscillator
circuit, a bistable circuit and a push-pull circuit. The oscillator
circuit oscillates to transform DC into a single-phase oscillating
signal. The bistable circuit splits the single-phase oscillating
signal into a N-phase stimulus signal and a S-phase stimulus
signal, both of which respectively activate magnetism of two side
magnetic members of the electromagnetic device and magnetism of
middle magnetic member of the electromagnetic device to alternating
switch between N-phase and S-phase. The two side magnetic members
and the middle magnetic member are attracted or repulsed by the two
magnetic members respectively to force the swing arms to swing
reciprocatingly. The higher the oscillating frequency of the
oscillator circuit is adjusted to, the higher the speed of the
switching between the N-phase and the S-phase of the
electromagnetic device is. The lower the oscillating frequency of
the oscillator circuit is adjusted to, the lower the speed of the
switching between the N-phase and the S-phase of the
electromagnetic device is. The push-pull circuit amplifies and
transports the N-phase stimulus signal and the S-phase stimulus
signal to the electromagnetic pump to force the swing arms of the
electromagnetic pump to swing effectively. The frequency converter
circuit is arranged to use DC to activate the swing arms of the
electromagnetic pump to swing reciprocatingly. The oscillating
frequency of the oscillator circuit is adjusted to change the swing
speed, the swing frequency and the swing amplitude of the swing
arms of the electromagnetic pump, to further change the discharge
pressure, the discharge flow of the electromagnetic pump, and the
relationship between the discharge pressure and the discharge flow.
The oscillator circuit could be connected to a button or a keypad,
which is arranged to adjust the oscillating frequency of the
oscillator circuit.
[0020] In another embodiment of the present invention, the
frequency converter circuit further comprises a modulation circuit,
which generates a single-phase oscillating signal. The N-phase
stimulus signal and the S-phase stimulus signal generated in the
bistable circuit are mixed with the single-phase oscillating signal
respectively to enhance the N-phase stimulus signal while balance
the S-phase stimulus signal, to further enhance the magnetic field
strength of the N-phase of the electromagnetic device. The
enhancement of the magnetic field strength of the N-phase of the
electromagnetic device further causes the swing arms swing inward
with a higher speed and a bigger force and swing outward with a
lower speed and a smaller force, thereby the discharge pressure and
flow of the electromagnetic pump is increased. The modulation
circuit is connected to a button or a keypad, which is arranged to
activate or adjust the modulation circuit. The DC inputted into the
frequency converter circuit could be supplied by an in-car
cigarette lighter, by a battery, or by a transformer rectifier
unit.
[0021] The nose-washing tool has a fluid inlet end with a handle
disposed thereon and a fluid outlet end with a spray nozzle
disposed thereon, wherein the cleaning solution is flown in from
the end with the handle and injected out from the end with the
spray nozzle. The spray nozzle is linked to a touch sensitive
switch, which is enabled to move forth and back. When the spray
nozzle is touched to the nasal cavity to be pressed, the spray
nozzle will inject the cleaning solution, and when the spray nozzle
leaves the nasal cavity, the touch sensitive switch moves back to
the original position immediately to make the spray nozzle could
not inject the cleaning solution.
[0022] The container has a containing space for storing a cleaning
solution and is communicated with the inlet tube of the
electromagnetic pump through a negative pressure channel. Thereby

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0063] Referring to FIGS. 10 to 18A and 18B, a nose cleaner
according to a preferred embodiment of the present invention is
illustrated, which comprises an electromagnetic pump 20, a
container 1 for storing a cleaning solution, a nose-washing tool 4,
and a frequency converter circuit 40, wherein the frequency
converter circuit 40 is provided on a circuit board 28 as shown in
FIG. 10.
[0064] The electromagnetic pump 20 has an electromagnetic device 27
on one side and a pump housing 21 on the other side, wherein the
electromagnetic device 27 is surrounded with coils and has a middle
magnetic member 272 and two side magnetic members 271, wherein the
width of the middle magnetic member 272 is larger that of the side
magnetic member 271. Each of two outside surfaces of the pump
housing 21 provides a stretchable and elastic bladder 24, which
further provides an swing arm 25 respectively thereon, wherein one
end of each swing arm 25 is disposed on the outer side of the pump
housing 21 and a magnetic member 26 is provided on the other end of
each swing arm 25 with a distance from the electromagnetic device
27. The inside of the pump housing 21 is divided into two chambers,
i.e. a first chamber 211 in the upper portion and a second chamber
212 in the lower portion. Although the first chamber 211 and the
second chamber 212 are arranged upper-and-lower in this preferred
embodiment, the two chambers could also be arranged forth-and-back.
The first chamber 211 is communicated with one or more inlet tubes
22 and the second chamber 212 is communicated with one or more
outlet tubes 23. Two check valves 241 and 242 are respectively
provided between the sides of the chambers 211, 212 and the
bladders 24. Due to the reciprocating swinging of the swing arms
25, the electromagnetic pump 20 draws a fluid into the chambers
from the inlet tubes 22 and then discharges the fluid from the
outlet tubes 23. The theory of the movement of the electromagnetic
pump 20 will not be detailed mentioned, as it has already been
illustrated in FIGS. 2 to 7.
[0065] A fluid container 1, as shown in FIG. 1, has a containing
space 11 therein for storing a cleaning solution and an upper
opening enabling an upper cover 12 to cover thereon. The upper
cover 12 has a connecting member 13 provided thereon for
communicating with the electromagnetic pump 20 through a negative
pressure channel 31. A suction member 14 made of soft material is
connected to a bottom of the connecting member 13 for providing the
cleaning solution stored in the containing space 11 of the
container 1 as a fluid source according to the present
invention.
[0066] As illustrated in FIGS. 13 and 17, the nose-washing tool 4
has a handle 60, which comprises a hollow channel 60A and a base
60B. The hollow channel 60A has a platform 61 on the top end, a
trepanboring 62 opened downwardly on the bottom edge, an insert
channel 63 disposed in the center portion of the platform 61 and
extended into the hollow channel 60A, and a connecting channel 64
with a smaller hole diameter coaxially connected on the bottom of
the insert channel 63, wherein the bottom portion of the connecting
channel 64 is exposed outside the bottom of the hollow channel 60A.
Referring to FIGS. 18A and 18B, the platform 61 has two arcuate
insert grooves 65 and two arcuate block grooves 66, which are
respectively symmetrically arranged on the platform 61 and centered
on the insert channel 63, wherein the arcuate insert grooves 65 are
respectively communicated with the arcuate block grooves 66. The
arcuate block groove 66 has a groove width smaller than that of the
arcuate insert groove 65 and has an arcuate resist groove 661
disposed on the bottom thereof, wherein the arcuate resist groove
661 has the same groove width as that of the arcuate insert groove
65. The base 60B has a covering member 67 mating with the
trepanboring 62, a channel base 68 for the connecting channel 64
drilling through to make the base 60B could assist and support the
end of the connecting channel 64 that the fluid inlet tube could
solidly connected with the end of the connecting channel 64 to
transport the cleaning solution into the connecting channel 64.
[0067] As illustrating in FIGS. 13, 15 and 17, an extension channel
70 has a channel body 71, a fixing base 72 disposed on the bottom
of the channel body 71 and extruded from the channel body 71 along
the radial direction and mated with the platform 61, a receiving
channel 73 disposed on the bottom of the fixing base 72 and mated
with the insert channel 63, and a head 74 disposed on the top of
the channel body 71. Referring to FIGS. 18A and 18B, the fixing
base 72 has two arcuate plates 721 and two arcuate blocks 722
respectively disposed on the bottom of the arcuate plates 721 and
radically extruded therefrom. The two arcuate plates 721 and the
two arcuate blocks 722 could respectively insert into the arcuate
insert grooves 65 and rotate toward the arcuate block grooves 66.
As a result, the arcuate blocks 722 are respectively located inside
of the arcuate resist grooves 661 on the bottom of the arcuate
block grooves 66, thereby the extension channel 70 could be quickly
assembled with the handle 60. For the same reason, if the extension
channel 70 needs to be changed, it is only needed to rotate the
extension channel 70 backward to make the arcuate plates 721 and
the arcuate blocks 722 respectively face the arcuate insert grooves
65. Then, the extension channel 70 could be drawn out upward. The
receiving channel 73 has a ring groove 731 disposed on the outside
surface thereof, which could be engaged with an O shaped ring 732
to make the receiving channel 73 could be tightly connected with
the insert channel 65 without leakage. An inner hole 711 is formed
inside of the channel body 71 and the receiving channel 73, wherein
the inner hole 711 is communicated with the connecting channel 64
and has the same diameter with that of the connecting channel 64.
The head 74 has a containing house 741 grooved at the end thereof
and engaged with the top end of the inner hole 711, thereby the
containing house 741 receives the cleaning solution flown in from
the receiving channel 64. Besides, the head 74 has a ring block 742
protruded at the end.
[0068] Referring to FIGS. 13, 15 and 17, a fixing head 75 has a
ring slot 76 mating with the ring block 742 to cause a guiding
house 78 formed inside of the fixing head 75, wherein the guiding
house 78 is communicated with the containing house 741. The head 77
further has a fluid outlet hole 79 disposed on the top and in the
center of the top, wherein the fluid outlet hole 79 communicates
the inner side and the outer side of the guiding house 7.
[0069] Referring to FIGS. 13, 15, 17 and 19A, a touch sensitive
switch 80 has a shoulder member 81 sliding along the guiding house
78, wherein a center shaft 82 is extended downwardly from the
center of the shoulder member 81. In order to avoid the bottom of
the center shaft to block the top of the inner hole 711 in the
extension channel 70, the center shaft 82 has a groove 821 disposed
on the bottom. The shoulder member 81 has a spindle 83 disposed on
the top thereof and extended upwardly from the center thereof in
such a manner that the spindle 83 could move forth and back in the
fluid outlet hole 79. The spindle 83 further has a spray hole 84
provided on the top and a fluid guiding hole 85 radically provided
on a portion towards the shoulder 81, wherein the fluid guiding
hole 85 is communicated with the spray hole 84, and the shoulder
member 81 is communicated with the guiding house 78 and a hole 86
of the containing house 741. The spindle 83 further has a hollow
spray nozzle 90 disposed on the top thereof. The spray nozzle 90
has a ring cover 91 arranged to cover the head 77, a sleeve 93
engaged with the top of the spindle 83, a through-hole 92
communicated the inner side and the outer side of the spray hole
84, wherein the spray nozzle 90 could also slid along the head
77.
[0070] A resilient element, which is embodied as a spring 100 in a
preferred embodiment of the present invention, has an end supported
on the bottom of the containing house 741 and another end supported
on the shoulder member 81 while the center shaft 82 is sleeved in
and extended along the spring 100, so that the shoulder member 81
is supported onto the inner top surface of the guiding house 78 due
to the force of the spring 100, thereby the hole 86 is closed by
the inner top surface of the guiding house 78 and the fluid guiding
hole 85 is closed by the inner surface of the fluid outlet hole
79.
[0071] Referring to FIGS. 13, 19A and 19B, when the spray nozzle 90
touches the nasal cavity, the spindle 83 of the touch sensitive
switch 80 is brought to move, and the shoulder member 81 overcomes
the predetermined force of the spring 100 and moves towards the
containing house 741, thereby the hole 86 and the fluid guiding
hole 85 could be communicated with each other through the guiding
house 78. Then the cleaning solution in the containing house 741
could be transported to the spray hole 84 and injected out from the
through-hole 92 of the spray nozzle 90, thereby the function of
cleaning nasal cavity could be achieved. When the user chokes due
to the nasosinusitis or the incapability of autonomous respiration,
the user merely needs to draw the spray nozzle 90 out from the
nasal cavity, and then the spring 100 will elastically comeback and
force the touch sensitive switch 80 to make the hole 86 closed by
the inner top surface of the guiding house 78 and to make the fluid
guiding hole 85 closed by the inner surface of the fluid outlet
hole 79, thereby the cleaning solution injected from the spray
nozzle 84 will be immediately turned off. Hence, the defect that
the cleaning solution always injects here and there can be
overcome.
[0072] The frequency converter circuit 40 comprises a voltage
reduction circuit 42, an oscillator circuit 43, a bistable circuit
44 and a push-pull circuit 46. The voltage reduction circuit 42
transforms the 12V DC inputted by the outside DC power source 41 to
5V DC, which is supplied to each circuit as the working current,
wherein the voltage reduction circuit 42 could be used to stabilize
the voltage. The oscillator circuit 43 could be a Schmitt
oscillator circuit, which oscillates to transform a 12V DC into a
single-phase oscillating signal with an oscillating frequency
between 43 Hz to 66 Hz. The bistable circuit 44 splits the
single-phase oscillating signal into a N-phase stimulus signal and
a S-phase stimulus signal, both of which respectively activate the
magnetism of the two side magnetic members 271 and the magnetism of
the middle magnetic member 272 to alternating switch between
N-phase and S-phase. Accordingly, the two side magnetic members 271
and the middle magnetic member 272 are attracted or repulsed by the
two magnetic members 24 respectively to force the swing arms 25 to
swing reciprocatingly to compress or expand the bladders 24
respectively. The push-pull circuit 46 amplifies the N-phase
stimulus signal and the S-phase stimulus signal to force the swing
arms 25 of the electromagnetic pump 20 to swing effectively to
further improve the power of the electromagnetic pump 20.
[0073] Referring to FIGS. 20 to 22, when the oscillator frequency
of the oscillator circuit 43 is adjusted to a lowest frequency such
as 43 Hz, the speed of the switching between the N-phase and the
S-phase of the electromagnetic device 27 decreases to further cause
the reciprocating swinging of the swing arms 25 to have a lower
speed, a lower frequency and larger amplitude, shown as W3 in FIG.
12. Due to the decrease of the swing speed of the swing arms 25,
the discharge pressure of the electromagnetic pump 20 decreases,
and due to the increase of the swing amplitude of the swing arms
25, the discharge flow of the electromagnetic pump 20 increases a
lot.
[0074] Referring to FIGS. 23 and 24, the higher the oscillating
frequency of the oscillator circuit 43 of the frequency converter
circuit 40 of the present invention is, the higher the speed of the
switching between the N-phase and the S-phase of the
electromagnetic device 27. That further causes the reciprocating
swinging of the swing arms 25 to have a higher speed, a higher
frequency and smaller amplitude, shown as W1 in FIG. 22. As the
swing arms 25 reciprocatingly swing with a higher speed and a
higher frequency, the frequency of the electromagnetic pump 20
correspondingly increases rapidly to increase the suction pressure
and the discharge pressure (positive pressure), and as the swing
arms 25 reciprocatingly swing with smaller amplitude, the suction
flow and the discharge flow of the electromagnetic pump 20 decrease
correspondingly. Accordingly, when the oscillating frequency of the
oscillator circuit 43 is adjusted to a middle frequency (such as 55
Hz), the reciprocating swinging of the swing arms 25 has a medium
speed, a medium frequency and a medium amplitude, shown as W2 in
FIG. 11. At this time, the discharge pressure and the discharge
flow of the electromagnetic pump 20 are medium.
[0075] In view of above, it is appreciated that the electromagnetic
pump 20 could have a lower discharge pressure and a higher
discharge flow by means of adjusting the oscillating frequency of
the oscillator circuit 43 to a lower frequency, and the
electromagnetic pump 20 could have a higher discharge pressure and
a lower discharge flow by means of adjusting the oscillating
frequency of the oscillator circuit 43 to a higher frequency.
Accordingly, when the above features are utilized in the nose
cleaner, the electromagnetic pump 20 is able to be adjusted to a
low frequency type, i.e. the type of low discharge pressure and
high discharge flow if the patient's nasal cavity is hurt. In other
words, the fluid pressure of the fluid injected from the
nose-washing tool 5 is small enough to avoid hurting the nasal
cavity and the fluid flow of the fluid is big enough to clean the
nasal cavity well. For the patients with more dirty things in the
nasal cavity, the electromagnetic pump 20 is able to be adjusted to
a medium frequency type with medium discharge pressure and medium
discharge flow or to a high frequency type with high discharge
pressure and low discharge flow in order to clean up the dirty
things.
[0076] Referring to FIGS. 25A and 25B, a frequency converter
circuit 40 of a nose cleaner according to a second preferred
embodiment of the present invention is illustrated, which further
comprises a modulation circuit 45 generating a single-phase
oscillating signal. The N-phase stimulus signal and the S-phase
stimulus signal generated in the bistable circuit 44 are mixed with
the single-phase oscillating signal respectively to enhance the
N-phase stimulus signal while balance the S-phase stimulus signal
and to enhance the S-phase stimulus signal while balancing the
N-phase stimulus signal respectively. That is to enhance the
magnetic field strength of the N-phase of the electromagnetic
device 27 while balancing the magnetic field strength of the
S-phase of the electromagnetic device 27 and to enhance the
magnetic field strength of the S-phase of the electromagnetic
device while balancing the magnetic field strength of the N-phase
of the electromagnetic device 27 respectively.
[0077] The modulation circuit 45 according to the second preferred
embodiment is arranged to enhance the magnetic field strength of
the S-phase of the electromagnetic device 27 while balancing the
magnetic field strength of the N-phase of the electromagnetic
device 27. Referring to FIG. 26, when the modulation circuit 45 is
activated, the two side magnetic members 271 of the electromagnetic
device 27 is switched to the N-phase and the middle magnetic member
272 of the electromagnetic device 27 is switched to the S-phase. As
the magnetic members 26 are set to have the outside surfaces of
N-phase and the inside surfaces of S-phase, the magnetic members 26
is a big attracted by the S-phase middle magnetic member 272 of the
electromagnetic device 27, which causes the swing arms 25 swinging
toward the middle with a higher speed and a bigger force.
Accordingly, the electromagnetic pump 20 has a higher discharge
pressure and a higher discharge flow. Referring to FIG. 27, the
middle magnetic member 272 of the electromagnetic device 27 is
switched to the N-phase and the two side magnetic members 271 of
the electromagnetic device 27 is switched to the S-phase. Due to
the mixing of the modulation circuit 45, the N-phase stimulus
signal is weakened to cause the N-phase middle magnetic member 272
of the electromagnetic device 27 to have a less powerful magnetic
field strength to repulse the magnetic members 26. That causes the
swing arms 25 swinging outwardly with a decreased speed and a
decreased force. Accordingly, the suction pressure and the suction
flow of the electromagnetic pump 20 are decreased. Thereby, when
the modulation circuit 45 is activated, the swing arms 25 swing
towards the middle with a higher speed and a bigger force
consistently while swing outwards with a lower speed and a smaller
force consistently. In the other words, the modulation circuit 45
is arranged to enhance the discharge pressure of the
electromagnetic pump 20, with which the nose cleaner could easily
clean the dirty things that are difficult to clean up.
[0078] Referring to FIGS. 32 to 33, at least one bubble generating
valve 6a is arranged in the fluid path between the container 1 and
the nose-washing tool 4. The bubble generating valve 6a comprises a
T-shaped three-way connecter 6 and a cap 7. The connector 6
comprises a first tube 61 extended vertically and second and third
tubes 62, 63 extended horizontally, wherein the first tube 61 is
communicated with the connecting member 13 of the container 1, the
second tube 62 is communicated with the soft channel 3 to allow the
soft channel 3 to draw the cleaning solution into the container 1
through the connecter 6 and the suction member 14, and the third
tube 63 has a threaded portion 632 for screwing with the cap 7, so
as to control the gas-flow rate of an air inletting opening 631
thereof as well as the opening or closing of this inletting opening
631, so that when the electromagnetic pump 2 draws the cleaning
solution into the container 1, outside air is drawn and sucked in
through the air inletting opening 631 to mix with the flowing
cleaning solution due to the negative pressure effect thereof and
thus the cleaning solution discharged from the nose-washing tool 4
substantially contains a large amount of air bubbles. As the
discharged fluid contains a plurality of bubbles, the bubbles can
generally contact with the nasal mucosa, so that when the bubbles
in the discharged fluid break, oscillating force is generated and
applied to the nasal mucosa to massage the mucocilia of the nasal
mucosa and clean the dirt in the nasal cavity as well, thereby the
cilia on the nasal mucosa can recover their regular movement
without the need of using strong pressurized fluid.
[0079] Referring to FIGS. 28 to 30, according to a preferred
embodiment of the present invention, the electromagnetic pump 20
and the circuit board 28 is embodied to be contained in a body 30,
which has a upper cover 301 and a lower base 302 connected with
each other, wherein the upper cover 301 has a ring groove member
303 disposed on the upper surface thereof for being inserted by the
bottom edge of the container 1 to support the contain 1 onto the
upper cover 301. The upper cover 301 further has a negative
pressure joint 33 communicated the inside with the outside and the
lower base 302 has a positive pressure joint 34 communicated the
inside with the outside. The inlet tube 22 of the electromagnetic
pump 20 is communicated with the inner end of the negative pressure
joint 33 through a negative pressure channel 31. The container 1 is
communicated with the outer end of the negative pressure joint 33
through a negative tube 3. The outlet tube 23 of the
electromagnetic pump 20 is communicated with the inner end of the
positive pressure joint 34 through a positive pressure channel 32.
The nose-washing tool 4 is communicated with the outer end of the
positive pressure joint 34 through a positive tube 2. Thereby when
the electromagnetic pump 20 is turned on, the cleaning solution in
the container 1 is drawn into the electromagnetic pump 20 through
the tube 3 and then injected out from the nose-washing tool 4
through tube 2.
[0080] Referring to FIGS. 29 and 31, the oscillation circuit 43 is
connected to a first button 37 or a first keypad 38 of the body 30,
as shown in FIG. 29. The first button 37 or the first keypad 38 is
arranged to activate the oscillation circuit 43 to turn on the
oscillation circuit 43 and to adjust the oscillating frequency. In
another embodiment, the modulation circuit 45 is connected to a
second button 371 or a second keypad 381 of the body 30, as shown
in FIG. 31. The second button 371 or the second keypad 381 is
arranged to activate the modulation circuit 45 generate a
single-phase oscillating signal and to adjust the single-phase
oscillating signal.
[0081] Referring to FIGS. 11, 12 and 34 to 36, the external DC
power source 41 of the embodiment includes a transformer rectifier
unit 47, a battery 48 or an in-car cigarette lighter with 12V DC
power source. The circuit board 28 further has a DC socket 29 for
connecting to a transformer rectifier unit 47, a battery 48 or an
in-car cigarette lighter 49. Hence, it is very convenient for the
users to use the nose cleaner of the present invention at home, in
care or in the suburbs by connecting the nose cleaner to a suitable
power source.
[0082] One skilled in the art will understand that the embodiment
of the present invention as shown in the drawings and described
above is exemplary only and not intended to be limiting.
[0083] It will thus be seen that the objects of the present
invention have been fully and effectively accomplished. It
